I currently have a laptop and a desktop PC, one for work, one for games, and I wish to use the same peripherals for both using TB3 somehow.

The ideal solution would be to have a Thunderbolt 3 splitter/switch but I couldn't seem to find a reasonably priced option or anything at all.

I recently purchased a BenQ PD2710QC, which has a Thunderbolt 3 dock built into it. It works beautifully with my laptop and peripherals but only has one TB3 input.

If I install a Thunderbolt 3 PCI-E card (like this Gigabyte Alpine Ridge Dual Thunderbolt 3 Type C PCI Card) in my desktop, plug one port in from my laptop and plug the other into the BenQ PD2710QC - could it work? Or is there a better way to approach this, besides changing cables every time?

So if I understand what you are asking you want to use the same keyboard, mouse, and screen on both

So there is this cool gadget called a KVM, this allows you to switch between your different devices, but you can't use your desktop and laptop at the same time

But there is a software solution, something I use is synergy https://symless.com/synergy I set my laptop right next to my desktop monitor and use the same keyboard and mouse on both at the same time

    Seconding Synergy, it's a great software solution for what you seem to be trying to accomplish. Do note that you don't have to pay for it; the core components are open source, and there are built versions through 1.8.8 available for download free, with some forks floating around that purge the activation requirements for some of the features.
